    Steel Socket Head Screws

    Image of Product. Front orientation. Socket Head Screws. Steel Socket Head Screws, Fully Threaded.

    Fully Threaded

    Made of alloy steel, these screws are the standard for high-strength fastening. Use them in high-load applications such as dies, presses, and heavy equipment. The deep, six-point socket keeps the hex key from slipping out and damaging the drive.
    Length is measured from under the head.
    Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

    Ultra-Low-Profile Steel Socket Head Screws

    Image of Product. Front orientation. Socket Head Screws. Ultra-Low-Profile Steel Socket Head Screws.
    Our lowest-profile socket head screws. At about one-third the height of standard ones, these fit in the tightest spaces and shallowest holes, reducing the risk of snagging. However, they aren't as strong as screws with larger heads. Tighten with a hex key.
    Length is measured from under the head.
    Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

    Stainless Steel Button Head Hex-Drive Screws

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Button Head Hex-Drive Screws.
    These button head screws won't corrode from moisture and chemicals, but they aren't as strong as alloy steel screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.
    Length is measured from under the head.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.

    Stainless Steel Pan Head Torx Screws

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Pan Head Torx Screws.
    The most corrosion-resistant pan head Torx screws we offer. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. With a deep six-lobe opening, the Torx drive prevents your driver from slipping and stripping the drive. Also known as star drives, they withstand more torque than slotted, Phillips, and hex drives.

    These screws hold up against corrosion, deter unauthorized access, and prevent your driver from slipping. With a security pin in the drive, you can only turn them with a tamper-resistant Torx driver. Also known as pin-in-Torx, the drive has a deep six-lobe opening that withstands high torque without slipping and stripping the drive. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals, but they're not as strong as alloy steel.
    Length is measured from the top of the head.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
    L-Keys—Turn screws by hand for more control and less chance of overtightening compared to power tools.
    Power Tool Bits—Pair these bits with your power tools to turn screws more quickly than manual tools.
